He pointed out that the research of this project would follow the basic research paradigm of "propose questions, analyze questions and solve problems". The general idea is to first put forward the urgent problem of sovereign security of big data, then analyze the problem itself, summarize the international sovereign security model of big data, and finally give the solution to the problem.

The leaders of the five sub-projects respectively report on the key problems to be solved, research ideas and the results to be formed. They said that they would carry out the research of big data sovereign security construction system according to the logical thinking of "demand investigation, theoretical system construction and security system design".

The reviewing experts believe that the project has important theoretical value and practical significance, and the logical relationship among sub-projects is clear, the research objectives and methods are clear, and the technical methodology is feasible. Experts suggest that it is necessary to strengthen multi-agent and multi-field cooperation, give full play to the collective effect, build a think tank with national influence in data governance and data security, put forward more targeted consultation reports for government, and make contributions to promoting the actual needs of the country.

Dongmei Xiao, head of the expert review group, made a summary of the opening meeting. She suggested that the project team should broaden their horizons and focus on major core issues, and strengthen international exchanges and cooperation; Strengthen theoretical construction in defining core concepts such as data sovereignty and data security; Pay attention to the landing of results, truly tap the value of "data sovereignty", and produce application results with visibility.
